The cell envelope establishes the epidermal h2o barrier, a layer of insoluble proteins around the internal surface of the plasma membrane.

Melanin granules from melanocytes transit in the lengthy processes into the cytoplasm of basal keratinocytes. This transfer happens by means of cytocrine secretion, exactly where keratinocytes phagocytose the tips of melanocyte procedures.
